CNC Surface Grinding 309S Stainless Steel from VT machining delivers precision 309S Stainless Steel parts made to your exact drawing. Surface grinding produces flat, parallel faces with fine finish using a horizontal abrasive wheel, with parameters tuned to 309S Stainless Steel, which is corrosion resistant, strong and hygienic.
CNC Surface Grinding Capability for 309S Stainless Steel
- Austenitic/martensitic grades
- Corrosion resistant
- Tolerance to ±0.01 mm
- Typical hardness 70–200 HB (annealed)
Machining 309S Stainless Steel with CNC Surface Grinding
309S Stainless Steel behaves predictably under CNC Surface Grinding once parameters are dialled in: machinability is moderate; work-hardens, so positive-rake tooling and steady feeds are used to avoid glazing, and we tune the operation accordingly.
We hold reference parameters for this grade, so repeat orders of 309S Stainless Steel run consistently from one batch to the next.
CNC Surface Grinding Quality & Inspection
We control quality throughout the process, not just at the end. In-process checks plus final inspection — including CMM where specified — keep every 309S Stainless Steel part to print. Inspection reports, material certificates and first-article documentation can be supplied on request.
CNC Surface Grinding Tolerances & Surface Finish
Ground 309S Stainless Steel reaches single-micron tolerances on size, flatness and parallelism, with surface finishes down to Ra 0.1–0.4 µm — and a near-mirror finish on suitable alloys.
Final tolerances are governed by the material's behaviour, wall thickness and overall stiffness. We give honest DFM feedback if a callout would be costly or better achieved another way.
Secondary Operations & Finishing
Finished 309S Stainless Steel parts can move straight into secondary operations under one roof. Typical add-ons are deburring, passivation, anodising, plating, blasting, polishing and laser marking. We coordinate the whole chain so you receive complete, inspection-ready parts.
Why 309S Stainless Steel?
309S Stainless Steel is chosen when a part needs what this grade offers — it is corrosion resistant, strong and hygienic. We confirm the grade and any temper or heat-treat condition with you before machining.
Design Tips for CNC Surface Grinding 309S Stainless Steel
We are happy to suggest design tweaks that improve manufacturability. Allowing adequate grind stock, specifying realistic flatness over the true datum, and relieving corners help us hit tight tolerances on 309S Stainless Steel efficiently. If you send your model early, we will return practical DFM feedback before you commit to production.
Applications of CNC Surface Grinding 309S Stainless Steel
Customers order CNC Surface Grinding 309S Stainless Steel components for everything from instrumentation to structural and functional assemblies. Whether you need a single prototype or recurring production volume, the same process discipline applies.

What is the typical lead time and minimum order for CNC Surface Grinding 309S Stainless Steel?
CNC Surface Grinding prototypes for 309S Stainless Steel can be produced quickly and scaled to series production. Send your drawing and quantity and we will advise lead time and any minimum order.
What tolerances can you hold for CNC Surface Grinding 309S Stainless Steel?
Achievable tolerances for 309S Stainless Steel grinding depend on the alloy, geometry and feature size. Grinding routinely holds single-micron tolerances on diameter, flatness and parallelism. Exact figures are confirmed against your drawing callouts.
How clean are the edges produced by CNC Surface Grinding on 309S Stainless Steel?
Machined 309S Stainless Steel edges are clean and to specification; edge-break or deburring is added when your drawing calls for it.
What surface finish is achievable on 309S Stainless Steel with CNC Surface Grinding?
Grinding can take 309S Stainless Steel to a fine finish — typically Ra 0.1–0.4 µm, and to a mirror grade on suitable alloys.
Can VT machining make custom 309S Stainless Steel parts to my drawing?
Yes. 309S Stainless Steel 309S Stainless Steel grinding is made to order from your CAD/2D drawing. Share your geometry, material grade, tolerance and quantity and we will confirm feasibility, lead time and pricing.
